It’s a cold winter night here in Hayward, and you’re a few weeks into using your furnace for the season. Suddenly, it stops working, leaving your home without heat. Or, maybe you see your energy bill spike. Or, something smells weird or you’ve been hearing strange sounds coming from the furnace. Why is the blower fan constantly running?

Truth is, there’s a lot that can go wrong with a furnace, and that’s why ABC Cooling, Heating & Plumbing offers professional furnace service to homeowners in Hayward and much of the Bay Area. In this blog post, we break down some of the most common signs that indicate that it’s time to have an expert ABC technician look at your system.

When something goes wrong with your furnace, call ABC for professional furnace service

Out-of-control energy bills

You think your furnace is running great. Your home is cozy, but you haven’t been doing anything excessive temperature-wise and you’ve been smart about turning it off during the day. Then, you open your November energy bill and your costs are much, much higher than you expected, and certainly far above where they were the previous year. If your heating use didn’t change, then what happened?

A mechanical or airflow problem with an otherwise great-functioning furnace can cause your system to work harder to heat your home, burning far more energy in the process. Take the system’s air filters, for instance: as they become clogged with dirt and dust, the furnace has to double its efforts to circulate the home through your vents into your living spaces. A mechanical issue could also cause constant cycling for the furnace, or a blower that runs continuously.

These energy bills can start to add up. Address the issue head-on by giving ABC a call for professional furnace service. You may also want to consider getting a new furnace: most furnaces last between 12-15 years, and an aging furnace can encounter performance issues as time goes on.

No heat, or limited heat

You turn up the heat in your home, but, after time passes, you notice that the thermostat isn’t changing. The furnace sounds like it’s running, but there’s no hot air coming out of the vents. This could be a sign that something is wrong with your furnace, or that it needs to be replaced through our furnace installation.

It’s possible that your furnace just has a clogged filter that is restricting airflow to your home’s ducts. However, the problem could be more serious. It might have a mechanical issue that is preventing it from operating properly, or that the thermostat is having issues connecting to the furnace. Listen for any noises or patterns. One common effect of a clogged filter is a furnace that keeps cycling on and off continuously, never really heating the space or sending heat through the vents.

Then, give ABC a call for professional furnace repair. Our experienced technicians will diagnose the problem and provide you with an upfront, honest estimate for how much the repair will cost. We’ll get heat going in your house in no time.

Strange noises or odors

As you might expect, any strange noises or odors coming out of your furnace and your home’s air ducts may indicate a serious problem. You shouldn’t be hearing any rattling, rumbling, grinding, or squeaking. Such sounds are a sign that something is wrong mechanically with the system, and ignoring them (if you can even sleep through them!) could be a mistake that could end up destroying the entire furnace for good. The best thing to do is to call ABC for emergency service. We don’t charge you anything extra for work on weekends or holidays, and our friendly techs are always willing to help you find the source of any obnoxious furnace noises—and provide you with the professional furnace repair you need.

Odors are another problem. It’s not uncommon to have odor problems as a result of dirty air ducts—our indoor air quality testing can help with this—but a burning smell or any smoke coming from your vents is obviously not a good thing. Turn off the system immediately and call ABC for emergency, professional furnace repair.
